During this course, participants will practice cementing calculations, as well as job design exercises and cement evaluation methods using real-life examples. Liner cementing and stage cementing jobs will be developed in the classroom. Cement design software will also be demonstrated.

At the End of the Course Participants will be able to :

• • Determination of casing loads for design HPHT wells purposes.
  • To design casing properties to meet burst, collapse, and tensile strength requirements
  • To conduct casing running operations safely and successfully
  • Specification of cement slurry properties and volumes to meet well objectives
  • Determination of best procedures for attaining successful primary cementing for HPHT wells

The workshop is intended for Graduate trainee, Drilling Engineers, Drilling Representatives, Drilling Fluid Engineers and Contractor Personnel, Drilling Supervisors. Cementing Engineers (Offshore and Onshore Personnel), well engineer, petroleum engineer and Technical Support involved with drilling operations and responsible for the development, planning and application of the well cementing and casing program.
